When to prune double angel's trumpet in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune double angel's trumpet
Cut back the previous season's growth, removing dead and damaged stems entirely and shortening remaining shoots to healthy outward-facing nodes. The double form is no harder to prune than the species — same Y-junction principles apply.
Brugmansia suaveolens 'Plena' (double-flowered) behaves like other angel's trumpets — it blooms on new wood so annual pruning promotes flowering. Prune in late winter or early spring, removing dead wood and cutting back leggy stems. Container plants can be hard-pruned before overwintering. Gloves are essential; the whole plant is toxic.

Why is UK pruning timing different from American advice?
Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
